UNITED STATES PATENT OFFICE ,WILBUB S. LEWIS, OF LAKEWOOD, OHIO,ASSIGNOR TO THE NESTLE LE MUR GOMFANY, OF CLEVELAND, OHIO, A CORPORATIONOF OHIO HAIR CURLER Application filed June 15,

My invention relates to curlers upon which strands of hair are coiledand stretched during the heating operation of permanent wavingprocesses.

In forming permanent waves 111 human hair, it is customary to divide thehair into strands which are coiled around curlers of desired design andsecured, and then stretched lengthwlse while secured 1n coiled relation.Such curlers are generally formed I rotated in either direction whilethe sections are moved longitudinally relatively. It is objectionable toadjust the sections lengthwise in order to rotate them relatively tostretch the strands of hair because of the additional operation whichrequires time. Sections which can be rotated in one direction only areobjectionable because operators become proficient in coiling the strandsin either one direction or the other, and with this class of curlers theoperator is required to coil the strands in one direction.

An object of my invention'is to provide a tension device for a curlercomposed of coaxially extending sections whichwill permit relativerotation of the sections in either direction without longitudinaladjustment and which will prevent the tension of the stretched hair fromrotating the sections relatively.

A further object of my invention resides in the provision of a simple,inexpensive curler which is comprised of relatively rotatable sectionswhich can be readily assembled together to prevent relativelongitudinal; movement.

These and other objects and the invention 1925. Serial No. 37,106.

itself will appear in the following detailed specification. T In theaccompanying drawings, Figure 1 is a side elevation of a curlerembodying my invention; Figure 2 is a longitudinal sectional view of thesame; Figure 3 is a side elevation of the rod section prior to assemblywith the tube section; Figure 4 isa transverse sectional view of theassembled curler taken on line 1 15of Fig. 2; and Figure 5 is t atransverse sectional view of the assembled curler taken on line 5-5 ofFig. 2.

Referring now to the drawings by characters of reference, 10 representsonesection of a curler which is a tube open at each end and preferablyformed of round metal. The other section 11 of the curler isprefer'ably'formed of metal and is in the form of a rod which is ofslightly less diameter than the interior wall'of the tubular section.

The rod section extends co-axially through the tube section, and isflattened at one end to provide a finger grip 12, which the operator cangrasp to rotatethe rod. The other end 1-3 of the rod projecting from thetube is also flattened vandis provided with a slot 14: in which astring, extending around a strand of hair can be secured. The flattenedends of the rod are formed of sufiicient width to also in diameter andprovided witha longitudinally extending slot 16 in which the clutch ortensioning mechanism is anchored. The tension mechanism Consists of twoleaf springs 17 and18, which have one end inserted in the slot16 in therod. The springs extend around the rod in oppositedirections and bearagainst the inner wall of the tube 10, being under sufficient tension tofrictionally prevent relative rotation of the rod and tube sectionsunless manual rotative pressure is applied. The rod can be rotated'ineither 95 direction when the operator grasps the end I 12 of the rodandexerts sufficient pressure to overcome the frictional tension exertedby the springs.

- ,The rod section 11 is preferably formed of 10 standard rod stock.Prior to assembly of the rod with the tube, the portion 15 is reducedand slotted and the flattened slotted end 13 is formed. The springs-arethen inserted in the slot 16 and are bent around the rod whereupon therod is inserted through the tube with the end 19 (Fig. 3) unforme'd.After such insertion the end 19 is flattened to provide the grip 12 andto retain the tube against longitudinal movement relative to the rod. Itwill, be understood that either one or both of the flattened ends 12 and13 could be formed after the rod, with the springs assembled, isinserted through the tube.

In utilizing the curler for a'waving process", a strand othair isgathered from the scalp, after being treated'with a'soitening solution,and is tied adjacent the scalp to the slotted encl13 of the red by astring. The free endof the strand is teen coiled tightly aroundthe tube,either over or nude" the StlIHQln a direction toward the grip 12 and istied tothe tube at the end of the coil. By holding thetube the coiledhair will be stretched by rotating the rod 11. T he spring tensionagaii'istthe tube is sufficient to prevent rotation of the curlersections, so that the tension of the stretched hair will not ro-' tatethe curl-er section'srelatively.

Various changes can be made in the structure described herein withoutdeparting from the spirit of my invention and the scope of what Iclaim.-

' What I claim is 1.. A curler for carrying and stretching strand ofhuman hair comprising a tube upon which a strand of hair is coiled andsecured, a red extending through said tube having an enlarged end towhich the strand of hair is secured adjacent the scalp, a finger grip atthe other end or" said rod for rotating said rod relative to said tubeto stretch the strand coiled on said tube, and laterally extendingfriction means disposed intermediate a side ot the rod and'said tube anddisposed inter-, mediate the ends of the tube for preventing the tensionoi said strand of hair from rotating said tube and said rod relatively.

2. A. curler rod, around which a strand of hair may be coiled in eitherdirection and stretched, comprising two co'axially extend ing rotatablemembers secured together to prevent relative longitudinal movement, anda spring secured to one of saidmembers at intermediate portion t er-eatand en" the other of said in} here at a ltneral suiiace thereof to putthe members under lateral tension, the tension of said spring aganst 1member being gr aterthan the tension of he stretched hair, one of themembers project ng beyond both ends of the other member and comprisingat one end a handle portion and at the other end a hair strai'idsecuring portion.

3; A carter around which a strand of hair may be wound in eitherdirection and stretched comprising a tube, a slotted rod extendingthrough said tube and having enlarged ends to prevent relativelongitudinal displacement of said tube therefrom, and a pair ofoppositely extending springs having one end anchored. in the slot insaid rod and frictionally bearing under tension against an inner wall ofsaid tube, said springs preventing' relative rotation of said tube androd until overcome by the manual rotation of said rod.

4. A curler for a strand of hair comprising a tube, a rod extendingthrough said tube, said rod having its projecting ends flattened afterinsertion through said tube to secure said tube against longitudinalmovement on said rod, one of said flattened ends providing a finger gripfor rotating said rod relative to said tube, said rod corn-prising aportion disposed midway of its length, spring-pressed into frictionalengagement against the inner walls of the tube.
